fwrite，fputs字節安全

我想通過POST發送數據到一個php頁面，我需要存儲字節完全一樣，但我無法做到這一點。當我發送138個字節，的fputs和fwrite返回133.fwrite，fputs字節安全

$fh = fopen($myFile, 'ab') or die("can't open file"); 
echo fputs($fh, $_POST['data'] ,strlen($_POST['data'])); 
fclosw

VB.NET：

Dim ar As System.Text.UTF8Encoding = New System.Text.UTF8Encoding 
Request.ContentLength = ar.GetByteCount(PostData) 
ContentType = "application/x-www-form-urlencoded" 
SW = New StreamWriter(Request.GetRequestStream(), ar) 
SW.Write(PostData)

-edit 這被加密的數據的功能

Public Function Encrypt(ByVal stringToEncrypt As String, ByVal key As String) As String 
    Rijndael.Key = SHA256.ComputeHash(ASCIIEncoding.ASCII.GetBytes(key)) 
    Rijndael.Mode = CipherMode.ECB 
    Dim Buffer As Byte() = ASCIIEncoding.UTF8.GetBytes(stringToEncrypt) 
    Return Convert.ToBase64String(Rijndael.CreateEncryptor().TransformFinalBlock(Buffer, 0, Buffer.Length)) 
    End Function

EDITED 例如原始加密字符串：

加密如何？你可以添加一個例子嗎？ – 2011-04-30 21:55:59

我沒有看到一個原因，這是行不通後：

$connection = fopen($file, 'ab'); 
fwrite($connection, urldecode($_POST['data'])); 
fclose($connection);
